STOP.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

1 Be it known that I, FRANK S. INGOLDSBY, a citizen of the United States, residing at St. Louis, State of Missouri, have invented a certain new and useful Improvement in Stops, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a simple, cheap and easily applied stop to limit the movement of an adjacent member.

' The stop is adapted for a variety of uses and is especially applicable in mechanism where there is a member liable to be displaced, as for example, a member on a shaft where there is some jarring longitudinally of the shaft or other force tending to displace the member.

As a particular use for the stop, I may cite its application to the door raising mechanism of dump cars wherein there are longitudinal shafts having raising arms, and these arms are liable to become displaced when the cars are violently coupled together.

My inventionnot only looks the member in place preventing shifting, but also looks the bolt which secures the stop.

The invention comprises the means by which I effect the above results. It is illustrated in the drawings hereof in a preferred form, which form is hereinafter V fully described.

In the drawings, Figure 1 is a side elevation of a portion of a shaft having keyed to it an arm and equipped with my stop, the final position of the stop being shown in full lines, and the original position of its free end in dotted lines. Fig. 2 is a similar View showing the position the stop takes when the arm cannot be forced into its regular position. Fig. 3 is a plan of the stop and its bolt, being in plane at right angles to Figs. 1 and 2 and looking down with reference to these figures. Fig. 4 is a section on the line 44 of Fig. 1. Fig. 5 is a perspective view of the stop removed.

Referring to the embodiment shown in the drawings, 10 represents a shaft and 11 an arm or other member embracing the same and keyed thereto by the key 12 which 00- eupies a keyway 13 in the shaft. This keyway comes to an abrupt shoulder 14 at one end and the large end of the key rests against such shoulder.

The stop member itself is indicated by 15, and consists of a sheet metal strip bent back and forth on itself, as shown. It is provided with a hole 16 through which passes a bolt 17 which secures the stop to the shaft on the side of the arm corresponding to the small end of the key, that is, on that side toward which the arm might move, the taper of the key preventing the arm moving in the other direction.

WVhen the stop is applied it is in the form shown in Fig. 5, having'its extreme portion 18 standing above the rest of the stop, as shown also in dotted lines in Fig. 1. After the stop in this condition has been secured to the shaft by the bolt, or tap-screw, 17, the portion 18 of the stop is hammered down coming into the final position shown at 19 in Fig. 1, and engaging at its extreme end with the head 20 of the bolt and at its first bend with the side of the arm 11. It will be seen that in this position the stop not only prevents the arm having any movement, but acts as a lock for the bolt, preventing it being unscrewed.

If the arm does not come into its extreme position shown in Fig. 1 (which may frequently result in comparatively rough work) the portion 18 of the stop may take the position shown in Fig. 2. In this position the stop acts also to hold the arm against displacement and to lock the bolt in the same manner it would if the parts came to their preferred position. If the arm should fall considerably short of attaining its preferred position, the end of the portion 18 of the stop may be easily cut off with a cold chisel to allow it to be bent .down into position. The head of the bolt makes an excellent anvil on which to out ofi the end of the member 18 when this is necessary. Where the range of variations for the arm is small, the portion 18 need never be out off and still may accommodate a number of positions of the arm.

There are two objects in making one or more folds of the stop under the head of the tap-screw as indicated by 21. First, these folds give more metal in shear against the shank of the screw, and second, they raise the outer arm 18 and the next ply 22 high enough to pass over the top of the key so that there will be no trouble in flattening the portion 18.

My stop is cheaply constructedand easily applied. It is simply necessary to turn in the tap screw and hammer down the portion 18 of the stop. When so placed, the arm and tap screw are both locked securely into position, while to remove the parts it is only necessary to pry up the portion 18 of the stop.

Having thus described my invention, I

claim 1. The combination, with a member, of a stop formed of a strip of sheet metal bent on itself, and a bolt having an angular head and arranged to secure said strip in such position that it may engage said member 7 ing the stop adapted to be engaged by such portion.

4. The combination with a supporting member and a second member thereon, of a stop comprising a sheet metal strip bent back and forth on itself and secured to the supporting member and adapted to engage the second mentioned member, and also look .the means for securing the stop.

5. The combination With a supporting member and a second member thereon, of a stop consisting of a metal strip bent on itself, a bolt for fastening the stop to, the supporting member and adapted to engage the second mentioned member and also engage and lock the bolt for securing the strip.

6. The combination of a shaft having a key-way, a tapered key occupying said keyway, a member held against rotation by the key, a stop, means for securing the stop to the shaft, said stop adapted to engage said member and also lock the securing means.

7. The combination of'a shaft having a key-way coming to an abrupt shoulder, a

. tapered key occupying such key-way with its large end against said shoulder, a member surrounding the shaft and said key, and a stop bolted to the shaft on the side where the small end of the key is, said stop being adapted to lock the member against move ment toward the stop and also lock the bolt against unscrewing.

8. The combination of a shaft having a key-way, a key occupying said key-way, a member, surrounding said shaft and key, a stop comprising a strip of metal bent on itself and bolted to the shaft, said strip having a free portion adapted to be hammered down between the side of the member and the head of the bolt.

9. The combination of a shaft having a key-way, a key occupying said key-way, a member surrounding said shaft and key, a stop comprising a strip of metal bent back and forth on itself and secured to the shaft, said strip having a free portion adapted to be hammered down against the side of the member, said strip bending on itself times enough to raise the free portion above the end of the key.

10. The combination of a shaft, a member slidable along the same, means for limiting the movement of said member in one direction, a stop for limiting the movement in the other direction, said stop consisting of a sheet metal strip bent on itself, means for securing said stop to the side of said shaft and parallel therewith, the stop engaging and preventing displacement of the securing means.
